Improvement in steam-pumps



charge-valve o is closed, and the valves Y opened, through which latterthe water rushes up, and follows piston M into cylinder A. As the pistonmoves upward, it carries with it the ring-valve Q, and any surplusuncondensedv steam, air, or gases are forced out through the valve V inthe head of cylinder A, until the shoulder on ring-valve Q comes intocontact with the shoulder on any ring-valve X, which is rigidly securedto rod E. The latter is elevated, bearing ringvalve X against the headof cylinder A, and closing the valve lV, at tl ie same time elevatingthe rod I, and opening valve H, through which steam is admitted, thusdestroying the vacuum in cylinder A, and above piston M.

The moment the vacuum isdestroyed, the water begins to fall by its owngravity, the pistou following, but the steam, exerting its force,whatever little force it has, on the piston, (the openings O ofwhich areclosed by ring-valve Q, which descends with the piston,) accelerates themomentum ofthe water, and the more, the deeper the water sinks in thecylinder'. the water begins to fall, the valves Y close, and valve 5opens, and allows the water to escape through pipe 7. Asthe pistondescends', the ring-valve Q strikes against the shoulder R on rod E, andopens the openings O in piston M, allowing the steam from cylinder A tofollow the momentum of the water, by passing, through the openings O,into cylinder B, the water in that cylinder, B, acting like a solidpiston, which, moving down in cylinder B, would createa vacuum, and.three the steam to follow it, where, mingling with the water, it israpidly condensed. At the same time, a moment after ring-valve Q hasstruck shoulder It, the bail S strikes against nut L onrod E, andcarries it dowm 'ard ith it, until piston M strikes at the bottom ofcylinder A, thereby removing ring-valve X from valve YV, and closingvalve H, thus shutting oif the steam from cylinder A. A vacuum is againformed in cylinder A, and the operation continues, as hereinbeforedescribed. l

The condensation ofthe steam, and consequent forming of a vacuum, arevery rapid, so rapid, in fact, that I have been enabled to make fifteenstrokes a minute,

with a pressure of from ten to fifteen pounds of steam, raising thewater a height of twenty-tive feet. The engine would operate were butlittle steam used, but

The moment.

not as rapidly,for the momentum of th'e water is accelerated by thepressure ofthe steam, t-liough'a greater amount of steam has to becondensed to create the vacuum, which is accomplished by the largesurta-cc ot' the coudelming-cylinder, this cylinder heilig kept vin acontinuous cool temperature, (the non-conducting packing between it andthe upper cylii'ider preventing the latter from heating the formen) andbeing almost continuously kept iilled with water.

By forcing out the surplus steam, air, or gases, through valve W in thehead of the cylinder A, by means of the momentum or concussion of thewater, I do away with air-pumps, siphons, and similar' contrivances, andthus simplify the construction and operation of my steam-condensingwater-elevating engine.

The rod E is balanced in suoli a manner, by means of the weight on thefree end of lever I, that the least amount of power is only required tooperate it.

Having thus described my invention,

What I cla'im as new, and desire to secm'e by Letters Patent, is-

l. A 'ater-elevatiug engine, having two cylinders, arranged one uponth'e other, the upper one for receiving the steam, which'aids inexpelling the water therefrom, and which, by means of its condensation,causes a vacuum to be created therein, and another, into which the steamfrom the latter is caused to ilow by the discharge ofthe water from thevfoi-mer, and in which the steam from the upper cylinder is condensed,substantia-ll' as described.

2. The combination of cylinders A and B and float or piston M, with itsapeitures or passages (l), substantia-lly` as described.

3. The combination ofthe float or piston M and valve P, substantially asset forth.

4. The combination of the rod E, float M, valves P, Q, and X,substantially as described.

5. The combination and arrangement of valves Q and X on rod E, and valveW in the head of cylinder' A, substantially as set forth.

(i. The arrangement of valve Hin relation and with reference to alves Xand lV substantially as set forth.
